The CurrentWatch EDC Series from
Eaton’s electrical business combines
a hall effect sensor and signal
conditioner into a single package for
use in DC current applications up to
300A. The EDC Series has jumper­selected current input ranges and
industry standard outputs: 4 – 20
mA, 0 – 5V DC or 0 – 10V DC.
Available in split-core models for
quick and easy installation.

For typical applications of the
CurrentWatch™ EDC Series, see

EDC Series Current Sensor

CA05311009E

Current Sensing for DC Loads up to 300A with Analog Outputs

Product Features

Jumper-Selectable Ranges — Reduces inventory and eliminates zero or

■

span pots

■

Isolation — Output is magnetically isolated from the input for safety, also

eliminating insertion loss (voltage drop)

■

Internal Power Regulation — Cuts installation costs and works well, even

with unregulated power

Split Core Design and Built-In Mounting Brackets — Makes installation

■

quick and easy

■

UL and CE Approved

Typical Applications

1

■

Battery Banks — Monitors load current, monitors charging current and

verifies operation

Transportation — Measures traction power or auxiliary loads

■

■

Electric Heating Elements — Monitors heater loads with a faster response

time than temperature sensors
